Cave formed beside the torrent bed from the accumulation of large collapse blocks; it has three distinct levels, interconnected with one another through the spaces between the different voids of the blocks.

The lower level is entered directly from the torrent through an open-air corridor that leads into the lower part of a distributor; from there, heading up some level of blocks, we will enter the main chamber, of considerable size. The chamber has some branches that quickly come to an end; only the branch heading up located to the N has an exit to the outside through a narrow passage. In the ceiling of the chamber the 3 possible connections with the upper level can be made out.

The upper level is easily entered by heading up the torrent, upstream of the lower level; the streambed narrows and we end up in an ascending gallery that is none other than the upper level of the cavity. In the floor there are two passages between blocks that connect directly with the ceiling of the lower chamber; the third connection is made through a crawlway that gives access to a small room, which also connects with the lower level by means of a lateral step.

At the end of the upper gallery, a window allows one to go out to the outside onto a small balcony over the lower distributor, and in the ceiling of the same gallery there are the connections that give exit again to the torrent and to the highest point of the whole cavity.
